Flexible Conduit (N.Bundy job)

I've used the term containment repeatedly in this thread as it's the only suitable collective noun I could think of

Well stop it nicey lol

I’ve watched a few of N Bundys YouTube videos and from what I’ve seen he seems a good domestic electrician. Someone like him would be ideal for knocking out new builds to a good standard and at a good pace....If he worked for you, he would definitely earn you a few quid. However l, I do think using the kopex, like he has was a poor choice. I bit of tray or trunking would of done the job or drilled the joists.

The word containment used to annoy me too, but I guess I have just got used to it over the years.

Yes conduit and trunking were originally designed for singles many many years ago, but that doesn't mean that's the only thing they can, or should, be used for.

steel conduit and galvanised trunking should really be used exclusively for singles imo As it was originally intended...
plastic conduit , kopex and plastic trunking can really be used for anything just to provide additional mechanical protection / cable containmen.
i do feel it has become almost frowned upon to clip cables on the surface , But imo there is nothing wrong with clipped surface

Its like most practises, that have become almost extinct in this industry, maybe too labour intensive.

So we should all be installing VIR singles? After all that is what galvanised trunking and conduit was originally intended for, PVC insulated cables hadn't been invented.

Why shouldn't we be able to put any cable type in galvanised conduit or trunking? If something needs the mechanical protection of steel conduit then put it in steel conduit, it doesnt matter whether is is singles or anything else.

I suppose minds could become a bit clouded dependant upon experience but one thing is for sure....you're absolutely spot on with that one.

i can’t disagree with that , I’m just saying steel conduit was designed for single cables to be pulled through it...

Same with galv trunking, eh?

again , I’m not saying don’t use it to contain various varieties of cables

I’m just saying it’s primary function was to contain single cables & should remain its primary function

It's primary function was, and still is, to provide good mechanical protection to cables. Other functions include providing a rewireable system.

Yes when it was first used it was only for single core cables, but only because that's all they had at the time.

These days we have a variety of cables which need that level of protection, including but not limited to, CAT5/6, sensor cables, fire alarm cables, telecoms, control systems cables, fibre optics.
